A 5-turn square loop (10 cm along a side, resistance = 4.0 W) is placed in a magnetic field that makes an angle of 30 with the plane of the loop. The magnitude of this field varies with time according to B = 0.50t2, where t is measured in s and B in T. What is the induced current in the coil at t = 4.0 s?
 a. 25 mA
  b. 5.0 mA
  c. 13 mA
  d. 43 mA
  e. 50 mA

Question 2

A planar loop consisting of four turns of wire, each of which encloses 200 cm2, is oriented perpendicularly to a magnetic field that increases uniformly in magnitude from 10 mT to 25 mT in a time of 5.0 ms. What is the resulting induced current in the coil if the resistance of the coil is 5.0 W?
 a. 60 mA
  b. 12 mA
  c. 0.24 mA
  d. 48 mA
  e. 6.0 mA
